ahal hit this test failure multiple times when trying to enable mochitest-plain in fission-xorigin mode on more platforms in bug 1694835:

Comment 7

[Edgar Chen [:edgar]]

test_bug1399605.html is a test for IntersectionObserver, so move to Layout.

Comment 8

[Chris Peterson [:cpeterson]]

Sending this bug to Layout triage. The Fission team hit this test failure multiple times when trying to enable mochitest-plain in fission-xorigin mode on more platforms in bug 1694835, so Fission and/or xorigin mode might make this infrequent intermittent failure (less than 10 failures per week) more frequent.

Comment 12

[Daniel Holbert [:dholbert]]

Looks like we've gone 3 weeks without any new reports. This failure-report from the start of the year until today (May 4) shows the most recent failure as being on April 12th, 3 weeks ago:
https://treeherder.mozilla.org/intermittent-failures/bugdetails?bug=1694536&startday=2021-01-01&endday=2021-05-04&tree=all

Maybe this is fixed?

Or, is there a reason these reports would have gone away, without this actually being fixed? (e.g. did we turn off some tests/platforms in a way that would've stifled this failure?)

I don't know of any bug fixes or platforms being disabled that might have made that test failure go away. We are currently trying to enable these M-fis-xorig tests on more platforms. I will resolve this bug as "fixed" for now.

Sounds good, thanks!
